<Embodiment 1>
Next, the work transfer support system according to the first embodiment will be described with reference to the drawings.

[Constitution]
FIG. 2 is a diagram illustrating the configuration of the work takeover support system according to the present embodiment. Referring to FIG. 2, the work handover support system includes a management server 1 and portable terminals 2A to 2C. The portable terminals 2A to 2C are connected to the management server 1 wirelessly (a wired section may be included in the middle).

In the present embodiment, as illustrated in FIG. 3, three workers 100A to 100C share and carry out work items included in the work of manufacturing the work object Pn (n = 1 to N). And Here, it is assumed that the worker 100A performs work on the most upstream side, and the worker 100B or the worker 100C on the downstream side takes over the work performed by the worker 100A halfway. In addition, the worker 100C takes over the work performed by the worker 100A or the worker 100B halfway. As shown in FIG. 3, workers 100A to 100C hold mobile terminals 2A to 2C, respectively. 2 and 3 are merely examples, and the present invention is not limited to the illustrated embodiment.

FIG. 4 is a block diagram illustrating a detailed configuration of the work handover support system (FIG. 2) according to the present embodiment. The mobile terminal 2 in FIG. 4 represents the mobile terminals 2A to 2C in FIG. In the following description, when it is not necessary to distinguish the mobile terminals 2A to 2C, these terminals are collectively referred to as the mobile terminal 2.

Referring to FIG. 4, the management server 1 includes a storage unit 11 and a communication unit 12.

The storage unit 11 stores a plurality of items included in the work and the work result of each item as work forms Dn (n = 1 to N) in association with each other. Here, it is assumed that the work form Dn and the work object Pn (see FIG. 3) have a one-to-one correspondence. FIG. 5 is a diagram illustrating the configuration of the work form Dn. Referring to FIG. 5, the work form Dn includes a “work item” for the work target Pn, a “work content (for reading)” read by the portable terminal 2 when each work item is voice-guided, and a work item. The “work result” that is the result of execution, the “worker ID” that identifies the worker, and the “terminal ID” that indicates the portable terminal that is the transmission source of the work result are stored in association with each other. Here, for the sake of simplicity, there are four work items for the work object Pn: “device model number (acquisition)”, “screw attachment on the device upper surface”, “screw loosening (confirmation) of the device”, and “device "Appearance abnormality (confirmation)".

The communication unit 12 transmits the work form Dn (n = 1 to N) to the mobile terminals 2A to 2C. Further, when the communication unit 12 receives the work result transmitted from each mobile terminal in response to the utterances of the workers 100A to 100C holding the mobile terminals 2A to 2C, the communication unit 12 holds the received work result in the storage unit 11 Record in form Dn. In addition, when the communication unit 12 receives a request for a work result from each mobile terminal, the communication unit 12 transmits the work result included in the work form Dn held by the storage unit 11 to the requesting mobile terminal.

When the communication unit 12 receives, from the portable terminal (for example, the portable terminal 2B), the request for the work result and the handover source information for identifying the handover source portable terminal or the worker (for example, the handover source information for identifying the portable terminal 2A), the communication unit 12 receives The work result received from the portable terminal indicated by the takeover source information or the portable terminal held by the worker (for example, the portable terminal 2A) is transmitted to the requesting portable terminal (for example, the portable terminal 2B).

When the communication unit 12 receives the object identification information (for example, Pn) for identifying the work object (for example, the work object Pn) together with the request for the work result from the portable terminal 2, the work object indicated by the object identification information. A work form Dn corresponding to Pn is selected from a plurality of work forms D1 to DN held in the storage unit 11, and a work result included in the selected work form Dn is transmitted to the requesting mobile terminal 2.

Referring to FIG. 4, the mobile terminal 2 includes a storage unit 21, a voice recognition unit 22, a communication unit 23, a work instruction unit 24, and a reading unit 25.

The storage unit 21 stores a plurality of items included in the work and the work result of each item in association with each other as a work form Dn. Here, for the sake of simplicity, the work forms Dn held by the management server 1 and the work forms Dn held by the portable terminal 2 are assumed to be the same. However, the worker ID and the terminal ID may be omitted for the work form Dn held by the mobile terminal 2. The storage unit 21 holds a plurality of work forms Dn (n = 1 to N) corresponding one-to-one with respect to a plurality of work objects Pn (n = 1 to N, FIG. 3).

The storage unit 21 holds takeover source information for identifying a takeover source mobile terminal or worker. Here, as an example, the takeover source information identifies the takeover source mobile terminal. FIG. 6 is a diagram illustrating takeover source information. FIGS. 6A to 6C show the takeover source information held in the storage unit 21 of the mobile terminals 2A to 2C, respectively. Since the worker 100A holding the portable terminal 2A is the most upstream worker (see FIG. 3), the takeover source terminal ID of the portable terminal 2A is blank (FIG. 6 (a)). On the other hand, since the worker 100B holding the portable terminal 2B is the worker who takes over the work of the worker 100A, the takeover source terminal ID of the portable terminal 2B is the identifier 2A of the portable terminal 2A (FIG. 6B). ). Similarly, since the worker 100C holding the portable terminal 2C is the worker who takes over the work of the worker 100B, the takeover source terminal ID of the portable terminal 2C is the identifier 2B of the portable terminal 2B (FIG. 6C). ).

The voice recognition unit 22 records the result of the voice recognition based on the operator's utterance in the storage unit 21. For example, the voice recognition unit 22 performs a voice recognition result based on the utterance (for example, utterance of “confirmation complete”) of the worker who has performed the work item “screw loosening (confirmation) of the device” on the work object Pn ( “Confirmation completed”) is recorded in the work form Dn held by the storage unit 21 (see, for example, the work form Dn in FIG. 7B). Further, the voice recognition unit 22 recognizes voices of other utterances (for example, “change”, “reload”, etc.) by the worker.

The communication unit 23 holds the work form Dn (n = 1 to N) received from the management server 1 in the storage unit 21. Further, when the voice recognition unit 22 recognizes a predetermined utterance (for example, “reload”) of the worker, the communication unit 23 requests the work result from the management server 1 and stores the work result received from the management server 1. To record. Further, when the voice recognition unit 22 recognizes a predetermined utterance (for example, “changes”) by the voice recognition unit 22, the communication unit 23 is included in the work form in which the worker among the work forms held by the storage unit 21 is working. The work result is transmitted to the management server 1.

When the communication unit 23 requests the work result from the management server, the communication unit 23 also transmits the takeover source information, and receives the work result transmitted from the portable terminal indicated by the takeover source information to the management server. Good. For example, the communication unit 23 of the portable terminal 2B held by the worker 100B, based on the utterance of the worker 100B with “reload”, the takeover source terminal ID “2A” indicated by the takeover source information (FIG. 6B). Is transmitted to the management server 1, and the work result transmitted from the portable terminal 2A to the management server 1 is received from the management server 1. According to such a configuration, the amount of work result information downloaded from the management server 1 to the mobile terminal 2 can be limited (reduced), and the work can be quickly taken over.

The work instruction unit 24 instructs the worker to execute an item whose work result is not registered in the work form Dn selected by the worker among the work forms D1 to DN held by the storage unit 21. Referring to FIG. 3, for example, when the worker 100B delivers the work object Pn from the upstream worker 100A, the work form Dn corresponding to the work object Pn is displayed as an incomplete work list on the display of the portable terminal 2B. The selected work forms D1 to DN (see FIG. 3) may be selected by voice input (or tap operation). For example, in the situation of the work form Dn shown in FIG. 7A, the work instruction unit 24 provides voice guidance on the work content (for reading) for the work item “screw loosening (confirmation) of the device”. Similarly, in the situation of the work form Dn shown in FIG. 7B, the work instruction unit 24 provides voice guidance on the work content (for reading out) for the work item “appearance abnormality (confirmation) of the device”.

The reading unit 25 reads object identification information (for example, Pn) for identifying the work object Pn. Various methods can be used as a reading method of the reading unit 25. For example, the reading unit 25 may read a barcode (one-dimensional or two-dimensional) attached to the work object Pn. Further, the reading unit 25 may acquire object identification information of the work object Pn using near field communication (NFC) from a tag or an IC chip attached to the work object Pn. .

The work instructing unit 24 stores a plurality of work forms D1 to DN held in the storage unit 21 for work forms (for example, Dn) corresponding to the work objects (for example, Pn) indicated by the object identification information read by the reading unit 25. It is also possible to select from the above and instruct the worker to execute an item whose work result is not registered in the selected work form Dn. In this case, for example, the worker 100B does not need to perform voice input or manually select the work form Dn corresponding to the work target Pn from the incomplete work list shown in FIG. According to such a configuration, it is possible to eliminate the labor of the operator and improve the work efficiency, and at the same time, it is possible to prevent the work form from being erroneously selected. In addition, according to such a configuration, for example, even in a production line in which various types are mixed, the operator does not need to select a work form but also selects a work form by mistake. Can be prevented.

When the communication unit 23 requests the management server for the work result held by the management server, the communication unit 23 transmits the object identification information read by the reading unit 25, and the work corresponding to the work object Pn indicated by the object identification information. The work result included in the form Dn may be received from the management server. For example, the portable terminal 2B held by the worker 100B transmits the object identification information read from the work object Pn by the reading unit 25 to the management server 1 based on the utterance of “reload” by the worker 100B. Only the work result included in the work form Dn corresponding to the work object Pn indicated by the object identification information is received from the management server 1 and included in the work forms D1 to Dn−1 and Dn + 1 to DN for other work objects. Work results are not received. According to this configuration, the work result downloaded from the management server 1 to the portable terminal 2 can be limited to the work result related to the work object Pn, and the work can be taken over quickly.

Similarly, when the worker 100C sets the portable terminal 2B held by the worker 100B as the takeover source terminal ID, the storage unit 21 of the portable terminal 2C holds the takeover source information shown in FIG. 6C (step S5). .

The worker 100A reads the object identification information of the work object Pn using the reading unit 25 of the mobile terminal 2A. The work instruction unit 24 of the portable terminal 2A selects a work form Dn corresponding to the work object Pn indicated by the object identification information from the work forms D1 to DN held by the storage unit 21. At this time, as shown in FIG. 5, since none of the work items included in the work form Dn has been performed, the work instruction unit 24 starts voice guidance “device model number” for the first work item. When the worker 100A checks the device model number and utters “ABC1”, the voice recognition unit 22 of the portable terminal 2A recognizes the utterance of the worker 100A by voice, and the storage unit 21 holds the voice recognition work result “ABC1”. Recorded as the work result of the corresponding work item in the work form Dn. Next, the work instruction unit 24 of the portable terminal 2A performs voice guidance “attaching screws to the upper surface of the apparatus and attaching them to four locations” for the second work item. When the worker 100A completes the screw installation work and utters “attachment complete”, the voice recognition unit 22 of the portable terminal 2A recognizes the utterance of the worker 100A and stores the voice recognition work result “attachment complete”. The work result of the corresponding work item in the work form Dn held by the unit 21 is recorded (step S6). FIG. 7A shows a work form Dn held by the storage unit 21 of the portable terminal 2A at this time.

Assume that the worker 100A determines that the remaining work items are to be taken over by the worker 100B or 100C when the second work item is completed, and utters “change”. When the voice recognition unit 22 of the mobile terminal 2A recognizes the speech of the worker 100A as “changes”, the communication unit 23 reads the work result (“ABC1” in FIG. 7A) from the work form Dn held in the storage unit 21. "Installation complete") is extracted and transmitted to the management server 1 together with the worker ID (100A in this case) (step S7).

When the communication unit 12 of the management server 1 receives the work result from the portable terminal 2A, it records it in the work result column of the work form Dn held by the storage unit 11 (step S8). Further, the communication unit 12 records the worker ID (here, 100A) who performed the work item corresponding to the work result and the terminal ID (2A here) of the work result sending source in the work form Dn (FIG. 7). (A)).

As shown in FIG. 3, the work object Pn is delivered to the worker 100B. The worker 100B reads the object identification information of the work object Pn using the reading unit 25 of the mobile terminal 2B. The worker 100B utters “reload” in order to acquire the work result of the handover source worker 100A. Then, the communication unit 23 of the mobile terminal 2B sends the takeover source terminal ID (identification information of the mobile terminal 2A) included in the takeover source information and the target object identification information of the work target object Pn together with the request for the work result to the management server 1. Send to. When the communication unit 12 of the management server 1 receives the work result request, the takeover source terminal ID, and the object identification information from the portable terminal 2B, the object identification information is selected from the work forms D1 to DN held in the storage unit 11. The work result Dn corresponding to the work object Pn indicated by is selected, and the work result obtained from the portable terminal 2A indicated by the takeover source terminal ID among the work results included in the selected work form Dn (of FIG. 7A) "ABC1", "attachment complete") is transmitted to the portable terminal 2B. The communication unit 23 of the portable terminal 2B records the work result received from the management server 1 in the work form Dn held by the storage unit 21 (step S9). Fig.7 (a) shows the work form Dn which the memory | storage part 21 of the portable terminal 2B hold | maintains at this time.

The work instruction unit 24 of the portable terminal 2B selects a work form Dn corresponding to the work object Pn indicated by the object identification information from the work forms D1 to DN held by the storage unit 21. At this time, as shown in FIG. 7A, since the first and second work items included in the work form Dn have been performed, the work instruction unit 24 provides voice guidance for the third work item. Start “Check 8 places for looseness of device screws”. When the worker 100B checks the looseness of the screw and utters “confirmation completed”, the voice recognition unit 22 of the portable terminal 2B recognizes the utterance of the worker 100B and recognizes the voice recognition work result “confirmation completed” in the storage unit 21. Is recorded as the work result of the corresponding work item in the work form Dn held by the user (step S10). FIG. 7B shows a work form Dn held by the storage unit 21 of the portable terminal 2B at this time.

However, the present invention described using this embodiment as an example is not limited to the configuration described above. The worker 100 </ b> B may employ a configuration in which the management server 1 is requested for a work result without using the reading unit 25 to read the object identification information. In that case, for example, as described above in the first embodiment, when the communication unit 23 of the mobile terminal 2B requests the management server 1 for the work result, the communication source 23 transmits the takeover source information, and is indicated by the takeover source information. The work result transmitted from the terminal to the management server 1 may be received from the management server 1. For example, the communication unit 23 of the portable terminal 2B held by the worker 100B, based on the utterance of the worker 100B with “reload”, the takeover source terminal ID “2A” indicated by the takeover source information (FIG. 6B). The management server 1 may be transmitted and the work result transmitted from the portable terminal 2A to the management server 1 may be received from the management server 1.

Assume that the worker 100B performs only the third work item, determines that the remaining work items are to be taken over by the worker 100C, and utters “change”. When the voice recognition unit 22 of the portable terminal 2B recognizes the utterance “change” of the worker 100B, the communication unit 23 reads the work result (“ABC1” in FIG. 7B) from the work form Dn held in the storage unit 21. "Installation complete" and "Confirmation complete") are extracted and transmitted to the management server 1 together with the worker ID (100B in this case) (step S11).

When the communication unit 12 of the management server 1 receives the work result from the portable terminal 2B, it records it in the work result column of the work form Dn held by the storage unit 11 (step S12). Further, the communication unit 12 records the worker ID (here, 100B) who performed the work item and the terminal ID (here, 2B) of the work result transmission source in the work form Dn (FIG. 7B).

As shown in FIG. 3, the work object Pn is delivered to the worker 100C. The worker 100C reads the object identification information of the work object Pn using the reading unit 25 of the portable terminal 2C. The worker 100C utters “reload” in order to acquire the work result of the handover source worker 100B. Then, the communication unit 23 of the portable terminal 2C sends the takeover source terminal ID (identification information of the portable terminal 2B) included in the takeover source information and the target object identification information of the work target object Pn together with the request for the work result to the management server 1. Send to. When the communication unit 12 of the management server 1 receives the work result request, the takeover source terminal ID, and the object identification information from the portable terminal 2B, the object identification information is selected from the work forms D1 to DN held in the storage unit 11. The work form Dn corresponding to the object Pn indicated by is selected, and the work result obtained from the portable terminal 2B indicated by the takeover source terminal ID among the work results included in the selected work form Dn (" Confirmation completed ”) and the work results obtained before that (for example, work results“ ABC1 ”and“ attachment completed ”obtained from the portable terminal 2A shown in FIG. 7B) are transmitted to the portable terminal 2C. The communication unit 23 of the portable terminal 2C records the work result received from the management server 1 in the work form Dn held by the storage unit 21 (step S13). FIG. 7B shows a work form Dn held by the storage unit 21 of the portable terminal 2C at this time.

The work instruction unit 24 of the portable terminal 2C selects a work form Dn corresponding to the work target Pn indicated by the target object identification information from the work forms D1 to DN held by the storage unit 21. At this time, as shown in FIG. 7B, since the first to third work items included in the work form Dn have been performed, the work instruction unit 24 provides voice guidance for the fourth work item. Start “Abnormal appearance of device”. When the worker 100C inspects the appearance of the apparatus and utters “confirmation completed”, the voice recognition unit 22 of the portable terminal 2C recognizes the utterance of the worker 100C, and stores the result of the speech recognition “confirmation completed”. 21 is recorded as a work result of the corresponding work item in the work form Dn held by the work 21 (step S14). FIG.7 (c) shows the work form Dn which the memory | storage part 21 of 2 C of portable terminals hold | maintains at this time.

When the worker 100C performs the fourth work item, all the work items included in the work are completed, so the worker 100C utters “alternate” (may be another utterance). When the voice recognition unit 22 of the portable terminal 2C recognizes the utterance “change” of the worker 100C, the communication unit 23 reads the work result from the work form Dn held in the storage unit 21 (“ABC1” in FIG. 7C), "Installation complete", "Confirmation complete", and "Confirmation complete") are extracted and transmitted to the management server 1 together with the worker ID (100C in this case) (step S15).

However, the present invention described using this embodiment as an example is not limited to the configuration described above. When the work instruction unit 24 determines that all the work items included in the work form Dn have been performed (that is, the work item has been completed), the communication unit 23 performs the work form Dn held by the storage unit 21. A configuration may be adopted in which work results are extracted from and sent to the management server 1 together with the worker ID.

When the communication unit 12 of the management server 1 receives the work result from the mobile terminal 2C, it records it in the work result column of the work form Dn held by the storage unit 11 (step S16). In addition, the communication unit 12 records the worker ID (in this case, 100C) who performed the work item and the terminal ID (herein, 2C) of the work result transmission source in the work form Dn (FIG. 7C).

(Operation example 2)

As shown in FIGS. 9A and 9B, the takeover source terminal IDs of the mobile terminals 2A and 2B are the same as those in the first operation example (FIGS. 6A and 6B). On the other hand, in this operation example, since the worker 100C holding the portable terminal 2C takes over the work of the workers 100A and 100B, the identifiers 2A and 2B of the portable terminals 2A and 2B are set as the takeover source terminal ID of the portable terminal 2C. (FIG. 9C).

Also in this operation example, the operation until the worker 100A executes the first two work items included in the work form Dn (FIG. 5) and transmits the work result to the management server 1 (steps S1 to S8 in FIG. 8). ) Is the same as in the first operation example. FIG. 10A shows a work form Dn held by the storage unit 11 of the management server 1 after the end of step S8.

Here, in FIG. 3, it is assumed that the worker 100B is temporarily absent, or the worker 100B delivers the work object Pn to the worker 100C without performing the work. At this time, the worker 100C reads the object identification information of the work object Pn using the reading unit 25 of the portable terminal 2C. The worker 100C utters “reload” in order to acquire the work result of the handover source worker 100A. Then, the communication unit 23 of the portable terminal 2C, together with the request for the work result, the takeover source terminal ID (identification information of the mobile terminals 2A and 2B) included in the takeover source information (FIG. 9C) and the work object Pn. The object identification information is transmitted to the management server 1. When the communication unit 12 of the management server 1 receives the request for the work result, the takeover source terminal ID, and the object identification information from the portable terminal 2C, the object identification information is selected from the work forms D1 to DN held in the storage unit 11.

FIG. 10A shows a work form Dn held by the storage unit 21 of the portable terminal 2C at this time.

The work instruction unit 24 of the portable terminal 2C selects a work form Dn corresponding to the work target Pn indicated by the target object identification information from the work forms D1 to DN held by the storage unit 21. At this time, as shown in FIG. 10A, since the first and second work items included in the work form Dn have been performed, the work instruction unit 24 provides voice guidance for the third work item. Start “Check 8 places for looseness of device screws”. When the worker 100C confirms the looseness of the screw of the apparatus and utters “confirmation completed”, the voice recognition unit 22 of the portable terminal 2C recognizes the utterance of the worker 100C and recognizes the voice recognition work result “confirmation completed”. Recorded as the work result of the corresponding work item in the work form Dn held by the storage unit 21. Next, the work instruction unit 24 starts voice guidance “Abnormal appearance of device” for the fourth work item. When the worker 100C inspects the appearance of the apparatus and utters “confirmation completed”, the voice recognition unit 22 of the portable terminal 2C recognizes the utterance of the worker 100C, and stores the result of the speech recognition “confirmation completed”. 21 is recorded as the work result of the corresponding work item in the work form Dn held by the work sheet 21. FIG. 10B shows a work form Dn held by the storage unit 21 of the portable terminal 2C at this time.

When the worker 100C inspects the appearance of the apparatus and utters “confirmation completed”, the voice recognition unit 22 of the portable terminal 2C recognizes the utterance of the worker 100C, and stores the result of the speech recognition “confirmation completed”. 21 is recorded as a work result of the corresponding work item in the work form Dn held by 21 (step S54). FIG.7 (c) shows the work form Dn which the memory | storage part 21 of 2 C of portable terminals hold | maintains at this time.

When the worker 100C performs the fourth work item, all the work items included in the work are completed, so the worker 100C utters “alternate” (may be another utterance). When the voice recognition unit 22 of the portable terminal 2C recognizes the utterance “change” of the worker 100C, the communication unit 23 reads the work result from the work form Dn held in the storage unit 21 (“ABC1” in FIG. 7C), "Installation complete", "confirmation complete", and "confirmation complete") are extracted and transmitted to the portable terminals 2A and 2B (step S55).

When the communication unit 23 of the portable terminals 2A and 2B receives the work result from the portable terminal 2C, it records it in the work result column of the work form Dn held by the storage unit 21. FIG. 7C shows a work form Dn held by the storage unit 21 of the portable terminals 2A and 2B at this time.

In each of the above-described embodiments, the operation when the work is performed without stopping the production of the work object Pn has been described as an example. However, in the production of the work object Pn, the work may be temporarily interrupted. For example, the interruption may be a break time of the worker or a case where a manufacturing failure (for example, an inspection error, an appearance failure, etc.) that cannot continue the production of the work target Pn occurs. When temporarily interrupting a worker during a break, the worker performing the work item performs a predetermined utterance (an utterance indicating that the work on the work item is interrupted, for example, “suspend”) To do. In this case, when the speech recognition unit 22 of the portable terminal held by the worker recognizes the speech “suspend” of the worker, the work result Dn of the work report Dn held by the storage unit 21 is retained. Record the work result of the corresponding work item. On the other hand, when the work is resumed from the temporary interruption, the worker performs a predetermined utterance (an utterance indicating that the work on the work item is resumed, for example, “resume”). In this case, when the voice recognition unit 22 recognizes the worker's utterance “resume”, the work instruction unit 24 starts voice guidance for the suspended work item included in the recorded work result.

In the following description, as an example, an operation when a manufacturing failure occurs and the work object Pn is lined out from the production line will be described. The worker performs a predetermined utterance (an utterance indicating that the work on the work item is interrupted, for example, “suspend”). In this case, when the speech recognition unit 22 recognizes the speech of the worker “suspend”, the speech recognition work result “suspend” is the work result of the corresponding work item in the work form Dn held in the storage unit 21. Record. In addition, the worker performs a predetermined utterance (an utterance indicating that the work is to be stopped, “stop”). In this case, when the voice recognition unit 22 recognizes the speech of the worker “stop”, the communication unit 23 transmits the work result included in the work form to the management server 1. However, for example, the communication unit 23 may transmit the work result to the management server 1 in accordance with an operation in which the worker taps the input unit in addition to the voice input.

[effect]
According to the work takeover support system of the present embodiment, the same effects as the work takeover support systems of the first and second embodiments are brought about. In addition, according to the present embodiment, work results accumulated in a certain portable terminal are directly sent to another portable terminal without going through the management server (or another portable terminal responsible for the management server function). Therefore, according to the present embodiment, the work result can be taken over to another portable terminal without delay. Further, it is not necessary for the takeover destination worker to make an utterance for acquiring the work result (for example, an utterance of “reload”), and the takeover work is simplified. Furthermore, according to the present embodiment, it is possible to avoid a load from being concentrated on the mobile terminal that functions as the management server as in the second embodiment. Further, according to the present embodiment, setting of the takeover source terminal is unnecessary, and the setting operation is facilitated.

<Modification of Embodiment 3>
In the third embodiment, when the voice recognizing unit 22 recognizes a predetermined utterance (for example, “changes”) of the worker, the communication unit 23 transmits the work result included in the work form that the worker is working on to another mobile phone. It was supposed to be sent to the terminal.

On the other hand, by adopting the configuration described below, it is also possible to omit the above utterance (“change”) by the worker. For example, the communication unit 23 uses the work result recorded in the work form Dn as a trigger when the voice recognition unit 22 recognizes the work result for the work item based on the utterance of the worker and records it in the work form Dn. To your mobile device. Note that work handover is performed in the same manner as in the third embodiment. That is, when the reading unit 25 reads the object identification information of the work object Pn, the work instruction unit 24 selects the work object Pn indicated by the object identification information from the work forms D1 to DN held by the storage unit 21. A corresponding work form Dn is selected, and voice guidance for an unexecuted work item included in the selected work form Dn is started.

As the worker grasps the change and takes over the work based on such a configuration, it is possible to omit utterances for handing over the work by the worker. In addition, when each work item is executed, when a work result is transmitted from the mobile terminal to another mobile terminal, communication occurs for each work item. However, the amount of data exchanged by communication in this case is only a small amount and does not affect the work efficiency.

Various modifications can be made to the work transfer support system according to the above embodiment. Hereinafter, these modifications will be described. However, the modification of the said embodiment is not limited to the following examples.

<Modification 1>
In the above embodiment, the takeover source terminal ID for identifying the takeover source mobile terminal is set as the takeover source information. However, instead of setting the takeover source portable terminal, a takeover source worker ID (for example, a worker number, a worker name, etc.) for identifying the takeover source worker may be set. In this case, when the management server receives the request for the work result from the portable terminal of the takeover destination worker together with the takeover source worker ID, the management server receives the request from the portable terminal held by the worker indicated by the work result takeover source worker ID. The work result is sent to the portable terminal of the transferee worker.

<Modification 2>
In the first and second embodiments, the takeover destination portable terminal downloads the work result from the management server (or the portable terminal responsible for the management server function). However, instead of downloading the work result, the takeover destination mobile terminal receives other information indicating the progress of the work (for example, information indicating the number of items included in the work, etc.) Or you may make it receive from the portable terminal which bears the function of a management server. Further, instead of exchanging work results between the mobile terminal and the management server, the work forms themselves may be exchanged.

<Modification 3>
In the above embodiment, for the sake of simplicity, there is one type of work object Pn (n = 1 to N) and the work form Dn (n = 1 to N) is also one type of form consisting of the same work items. explained. However, the above embodiment can be similarly applied to a case where a plurality of types of work objects and a plurality of types of forms are included.

<Modification 4>
In the first and second embodiments, when the mobile terminal recognizes the utterance of the worker (for example, “reload”), the work result is downloaded from the management server (or the mobile terminal responsible for the management server). did. However, the mobile terminal may download the work result by accessing the management server at a predetermined timing (for example, a predetermined cycle) regardless of whether or not the worker utters.
